Bad treatment

I paid for my beamie tracking device o Mix Telematics upfront, a month later, I upgraded the tracking device to an mx3 as my vehicle was going to work as taxify and needed a detailed report of the vehicles movements and other related information.

I took note that Matrix was debiting my account with monthly subscriptions which shouldn't have been the case as I had upgraded and had paid upfront, then I contacted them before the country went into lockdown to review this scenario and refund me all the debits posted.on my account which dates back to August 2019, I have been tossed from pillar to pillar after it was.confirmed by them that they would refund the money, I have been on an ongoing basis contacting them via emails to get answers when I will be refunded, up to this stage I have received my refund and I'm not getting any feedback even from their senior managers who are copied on emails going back and forth between myself and Matrix.

I am disgusted by this treatment and would like matrix to cancel my contracts and remove their tracking devices from both my vehicles.
